Agno supports using MongoDB as a storage backend for Agents using the `MongoDb` class.

## Usage

You need to provide either `db_url` or `client`. The following example uses `db_url`.

### Run MongoDB
Install [docker desktop](https://docs.docker.com/desktop/install/mac-install/) and run **MongoDB** on port **27017** using:
```bash
docker run -d \
  --name local-mongo \
  -p 27017:27017 \
  -e MONGO_INITDB_ROOT_USERNAME=mongoadmin \
  -e MONGO_INITDB_ROOT_PASSWORD=secret \
  mongo
```

```python mongodb_for_agent.py
from agno.agent import Agent
from agno.db.mongo import MongoDb
from agno.tools.duckduckgo import DuckDuckGoTools

# MongoDB connection settings
db_url = "mongodb://localhost:27017"

db = MongoDb(db_url=db_url)

agent = Agent(
    db=db,  
    tools=[DuckDuckGoTools()],
    add_history_to_context=True,
)
agent.print_response("How many people live in Canada?")
agent.print_response("What is their national anthem called?")
```
